I can not answer about the way to the title, but I have some insight about 'chess talent' by hanging with (very) strong players. Most of the times, talent in chess can be spotted by the ability to see things fast and to recall details :
I show a recently played OTB game to some guy who is 2200+, and in a fraction of seconds he sees the combo I spent 3 minutes calculating during the game, You show some typical endgame manoeuvre to a group of young chess players, then you set up exercises : the industrious youngsters solve the exercises similar to the examples you've shown, the talented young player solves the study with a twist... GM Cvitan plays a blitz game and at some stage he plays what seems like a dubious move...We think it was a lapse, so at the end of the game, we ask him - he sets up the exact position in a matter of seconds and show almost instantly the 4-5 moves tactical sequence which refutes our suggestion : that's GM talent...I should add that the ability to calculate fast and accurately is also a good sign of chess talent (not the only one, but certainly a good one )
I met with a club-member a day or two after our regular club meets and he asked about a game... I set up the exact position from an endgame and we analysed it. I'm also able to play out a few whole games (but I have to start at the beginning and can't do it with every game I played).
I think it's funny when people associate such things with titled players, class players can do things like this too.
Recognizing patterns (tactical or strategic) is something ever class of player is better at than the one before. A group of lesser GMs can analyze for hours to find the correct idea when a WC might see it in passing... I think there are some anecdotes about Botvinnik doing something similar. A GM just finishes setting up a position that was giving him trouble even after a few hours of analysing, and Botvinnik, still sitting across the room, says he sees 2 ways to win.
I don't care what anybody says. Not everybody has the talent to become an IM, no matter how much they study, just like not everybody has the talent to become a great artist, no matter how much they paint. Get some common sense, people!
